We describe a procedure for locating black hole horizons in Kerr-Schild spacetimes in the double copy paradigm. Using only single- and zeroth-copy data on flat spacetime, our procedure predicts the existence of trapped surfaces in the double-copy gravitational solution. We show explicitly how this procedure locates the horizon of the Schwarzschild black hole and the general Myers-Perry black hole.

  1. Black Hole Interiors as a Laboratory for Time-Dependent Classical Double Copy

    hep-th 2026-04 unverdicted novelty 7.0

    Trapped black hole interiors admit exact time-dependent classical double copy via Kantowski-Sachs patches from static Kerr-Schild data, characterized by p_parallel = -ρ, with finite single-copy fields in regular solut...

  2. Non-topological solitons in biadjoint scalar field theory

    hep-th 2026-06 unverdicted novelty 6.0

    Biadjoint scalar theory admits a family of non-topological solitons carrying U(1) charge, time-dependent like Q-balls, stable in truncation, with finite localized energy.

  3. Minisuperspace Double Copy in Lifshitz Spacetimes

    hep-th 2026-04 unverdicted novelty 6.0

    A radial operator extracted from the reduced gravitational dynamics in Lifshitz spacetimes directly reproduces the Maxwell operator for the temporal single-copy field without using equations of motion.

  4. Hawking Radiation meets the Double Copy

    hep-th 2025-10 unverdicted novelty 6.0

    Bogoliubov coefficients from scattering a scalar in a collapsing EM background (single copy of Vaidya) match ray-tracing results and connect to Hawking radiation through the double copy.
